The Fly tool is used in ArcScene to fly through a scene. The speed is relative and goes from negative numbers (backward) to positive numbers (forward). Sometimes these speeds need further tuning.
Start ArcScene with a surface visible.
- Click the Fly tool.
- Single-click the left mouse button. This is speed 1.
- While flying, use the up arrow key to increase speed 1. Use the down arrow key to decrease speed 1. Speed 1 will be recalibrated.
